摘要： One aspect of the invention involves: maintaining a record of how long a circuit operates in each of a plurality of different operating modes thereof, starting from a point in time at which a battery that powers the circuit is replaced; calculating for each of the operating modes as a function of the record a cumulative current drain from the point in time to a current time; and determining as a function of the cumulative current drains whether the battery is subject to a low voltage condition. Another aspect involves: monitoring a voltage of a battery; periodically determining whether the voltage of the battery is subject to a low voltage condition; and maintaining a count of the number of times that the determining results in a determination that the battery is subject to a low voltage condition.

摘要： An apparatus (10, 240, 300) includes a signpost (11, 241-256, 322, 612, 623, 626-628, 652, 661, 682, 686, 703) which transmits signpost signals (24) that are received by a tag (12, 271-275, 301-316, 395-397, 616-618, 641-643, 653, 656-657, 662-664, 679, 708, 711). The tag in turn transmits radio frequency beacon signals (72) which are received by a reader (13, 261, 319, 521-530). The tag can vary the duration of the beacon signals, for example in dependence on whether it is currently receiving a signpost signal. Further, the tag can dynamically vary the transmission rate and/or transmission power of the beacon signals, for example following receipt of a signpost signal. Varying these parameters can facilitate compliance with governmental regulations.

摘要： A tag can switch between first and second modes of operation, and consumes less power in the first mode. In the second mode, the tag can receive wireless signals having successive first and second portions. If the tag identifies a repetitive pattern of the wireless signals, the tag ignores the second portions of the signals. Otherwise the tag receives the second portions. In another embodiment, while in the second mode, the tag can receive wireless signals having successive first, second and third portions. The tag switches between the first and second modes at one rate until it detects the first portion, and then switches at a higher rate until it detects the second portion, and then stays in the second mode and receives the third portion.
摘要翻译：标签可以在第一和第二操作模式之间切换，并且在第一模式中消耗较少的功率。在第二模式中，标签可以接收具有连续的第一和第二部分的无线信号。如果标签识别无线信号的重复模式，则标签忽略信号的第二部分。否则标签接收第二部分。在另一个实施例中，在第二模式中，标签可以接收具有连续的第一，第二和第三部分的无线信号。标签以一个速率在第一和第二模式之间切换，直到它检测到第一部分，然后以更高的速率切换，直到它检测到第二部分，然后保持在第二模式并且接收第三部分。
